Background: Respiratory tract diseases are one of the leading causes of morbidity and mortality in young children, and a great variety of viruses are responsible of these infection. Objectives: To determine the infection rate of human bocavirus in children with lower respiratory tract infection and related with different variable. Patients and methods: Cross sectional study consists of 122 children under five years old their age ranged between 1 and 60 months and 75 males and 47 females; suffering from lower respiratory tract infection. They were attending respiratory wards in Fatima Al
Quantification of chimerism after bone marrow transplantation is essential for evaluation the successful of engraftment after allogenic stem cells transplantation. The aim of this work is to use STR typing test for identification and quantification the chimerism in bone marrow transplant patients. Two patients subjected to bone marrow transplantation were analyzed. DNA extracted from patients (recipient) blood, cheek swabs and donor cheek swabs. Quantifiler Real time PCR kit was used for DNA quantification. Powerplex21 kit was used for amplification STR loci. STR profiling was performed by Genetic analyzer. DNA extraction and quantification were successfully performed with suitable quantity and purity. STR loci fully amplified and analyzed. In both cases recipient and Donor shared alleles with no DNA mixtures. Few loci showed Type 3 chimerism. In conclusion the results showed that the test successfully identify used for identification and quantification of chimerism in recipient patients. List of abbreviation: DNA= Deoxyribonucleic acid, STR- short tandem repeat, SCT= stem cells transplantation.
Introduction and Aim: The zinc finger protein 804A (ZNF804A) gene has garnered significant interest as a gene associated with an increased risk of psychosis. This interest stems from the strong association observed between a specific single nucleotide polymorphism (SNP), namely rs1344706, within the ZNF804A gene, and various psychosis phenotypes, including schizophrenia and bipolar disorder. In this study, we aimed to assess the functional impact of ZNF804A gene polymorphism in individuals diagnosed with schizophrenia and methamphetamine addiction. Materials and Methods: This nested case control research included 50 individuals with schizophrenia and 50 methamphetamine (crystal) users recruited from Ibn-Rushed Psychiatric Teaching Hospital in Baghdad. 50 healthy subjects were also recruited as a control group. All participants were subjected to thorough physical examination. The serum concentration of Zinc Finger Protein-804A (ZNF804A) was determined using a sandwich enzyme-linked immunosorbent assay. Genomic DNA was isolated from whole blood samples, and the Taqman allelic discrimination method was used to genotype the ZNF804A gene rs1344706 polymorphism. Results: Patients with schizophrenia had a significantly higher median level of ZNF804A (48.67 ng/L) than controls (25.56 ng/L) or methamphetamine users (35.62 ng/L). The SNP rs1344706 homozygous (AA) genotype was more common in schizophrenia patients (36% vs. 16%) and methamphetamine addiction patients (4%), with significant differences (OR= 1.32, 95%CI= 1.32-11.75, p=0.014 and OR= 11.7, 95%CI=02.43-56.4, p=0.002, respectively). Conclusion: The AA genotype of rs1344706 polymorphism could be considered a risk factor for schizophrenia but has a protective role against methamphetamine addiction. Serum level of ZNF804A could be used to confirm the diagnosis of schizophrenia in young individuals with subtle clinical features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
